Bugs to be sure, but then who opens their windows with the comfort and ease of central heating and air conditioning?
In 1822 the American Farmer catalogue offered mesh cloth screen to keep bugs out of your home, and of began the humble window screen that allowed windows to be opened in the heat of summer to cool your house. Before medicine improved and pollution dis-improved you were told to go outside and breathe the clean air for your health.
Today the screen allows you to breathe the air without getting bit by bugs and mosquitoes, and while you are doing that you are airing pollutants out of your home. Modern building products, cleaning products, cigarettes, vapes, air fresheners, gas stoves and just living in the air tight space all add pollutants to the air, so airing out your home regularly is a must.
That humble screen wants you to open your windows every now and then, get a cross breeze by opening windows in front and back, top and bottom. So if your screens are damaged or missing this is a good time to get them repaired and back in your windows.
